10 Times The X-Files Mythology Confused Fans

10. The Black Oil’s Inconsistent Behaviour

In the X-Files series three classic, Piper Maru, viewers were introduced to the black oil; an alien goo capable of infecting humans and controlling their actions. Alex Krycek learned this the hard way when the oil jumped into his body and used him to help locate a spacecraft.
